Houston died on Feb. 11, 2012, in her fourth-floor hotel room of the Beverly Hilton Hotel, the night before the Grammy Awards. Her cause of death was ruled an accidental drowning, with heart disease and cocaine use listed as contributing factors.

Brian Weir, a senior patrol sergeant who was also at the scene, made the statements in a claim that accuses the police department and city of taking retaliatory actions against him after he reported the misconduct.

Weir's filing also claims that after Nuttall arrived, he, "for no legitimate law enforcement inquiry, investigative, or other proper and legal purpose... removed the sheet and/or other covering from the body... to an area below the pubic region."

"We will be looking into the allegations made in this claim, but we were not aware of any inappropriate behavior or comments made by any officer at the scene," Beverly Hills Police spokesman Lt. Lincoln Hoshino told CNN Wednesday.
